Black strips across roads

By Evil_Kitten 27 September 2012 36

What are the temporary black strips across roads for?

There’s usually two of them parallel to each other and they’re attached to a box that’s off the road.

Are they just to monitor the amount of traffic?

Are they speed related in any way?

What’s Your opinion?

They know the exact weight, tyre pressure and axle length of white holden commodores, then they automatically sms the police to alert them of a crime about to take place.

“Are they speed related in any way?”

The cynic in me believes you were speeding, saw them, and are now dreading a ticket 🙂

I never said anything about being a renegade. You are a little bit strange.

What’s with all the black hatch, jam tin, etc comments people? Is it because of “old” comment? I’m no spring chicken myself so don’t get your panties in a knot ladies!

5-10km over, like most normal people

Wow. You’re clearly as black-hearted and full of feline cunning as your account name suggests to be able to pull that off. What’s it like to be the coolest super villain of our time? It must be awesome being such a renegade.

More probably a grey import ricer with shiny mags

I’m gonna say a Golf. GTD, maybe an R. That, or a Suzuki Swift.

You buy your jam in tins?!

No, but I assume caterers and the like do.

I haven’t seen them around for ages on supermarket shelves though. I assume it’s because they were all bought up by 18 year-olds to replace the mufflers on their ricers.

Hahaha I bet you drive a black hatch and wear enormous sunglasses and have nothing to prove at all

More probably a grey import ricer with shiny mags, a doof machine and a jam tin exhaust.

You buy your jam in tins?!

Hahahaha! Someone got a guilty conscience?? 🙂

What is your definition of speeding,5,10,15,20 km/h over the limit or there are those i see who exceed the limit anywhere from 50 to 100 km/h.

5-10km over, like most normal people who spend more time being aware of the traffic and conditions around them, rather than staring at the speedo in fear of going 1km over.

A black hatch? wtf? lol

Surely they use the two strips to determine which way vehicles are traveling?

Calculating speed would be fraught with danger based on tyre pressures, tyre size etc all impacting the tyre footprint on the road and hence the time between hitting the two rubber hoses which appear to be no more than 1ft apart?

Ok – I just thought about that for a minute and realised it could work as a speed checker if the two tubes were close and the tubes were recording the front tyre/s hitting the first tube, then the front tyre/s hitting the second. No need to worry about chassis length or the rear tyres.

Then, since you know the speed of the vehicle, and the amount of time between the two (or more) axles hitting the tube, you can calculate the wheel base of the the vehicles using the road. I don’t actually know if they bother to do this, but the maths is simple.

I used to think that was the case until I had a closer look one day and discovered that one end of the tubes seems to be planted in the ground. So I asked a nearby Ranger and he confided that they are in fact nitrogen fertilisers for nearby trees. Since air contains 70% nitrogen, a pressurised injection of nitrogen laden gas (air) to the roots saves on fertiliser. If you look at just about any of these installations you’ll see that there is usually a tree nearby, often in less than perfect condition. Just be glad your driving habits are contributing to the nation’s trees bit by bit.

Best answer ever.

Dougal said :

But seriously, has anyone ever received a speeding fine this way?

If Snapper is correct and it was only used until the early 1990’s then that would only be people willing admit they’re really really old.

Anyone? 😛

I received an Amphometer fine in Captain Cook Crescent in 1987. Going 75 in a 60 zone. I wrote to the head of traffic services (pre self-government) claiming a lack of signage and the fine was withdrawn. I don’t think they’d be so lenient nowadays.

I didn’t even think of this, but spot on! There are signs up saying the suburb is being resealed very soon!

Enjoy your CrapSealed roads. I wish they had left ours alone.
